VILLIAM Y. OBER, OF LYNN, MASSACHUSETTS, ASSIGNOR TO THE STANDARD MININGAND VENTILATING COMPANY, OF PORTLAND, MAINE.

VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 409,224, dated August20, 1889.

Application filed February 8, 1889. Serial No. 299,166. (No model.)

To (tZZ whom it may concern.-

Be it known that I, \VILLIAM Y. OBER, of Lynn, in the county of Essex,State of Massachusetts, have invented a certain new and usefulImprovement in Ventilators, of which the following is a descriptionsufficiently full, clear, and exact to enable any person skilled in theart or science to which said invention appertains to make and use thesame, refer- IO ence being had to the accompanying drawings, formingpart of this specification, in which- Figure 1 is a sectional view of abuilding provided with my improvement; and Figs.

r5 2 and 3, enlarged views of a portion of the pipe, illustratingcertain details of construction.

Like letters and figures of reference indicate corresponding parts inthe different fig- 2o ures of the drawings.

My invention relates to that class. of ventilators which are providedwith disinfecting material; and it consists in certain novel features,as hereinafter fully set forth and claimed, the object being to producea simpler, cheaper, and otherwise more desirable device of thischaracter than is now in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

In the drawings, A represents the building, and B the rotary power fanor blower.

The blower B is of the ordinary form and construction, and is actuatedby an electric dynamo or engine F, being connected therewith by a belt,2. The blower is preferably situated in the basement of the building A,

0 and is provided with an induction-pipe so,

which passes through the wall I) of the building, and through whichfresh air is supplied. An eduction-pipe 41 leads from the blowervertically through the different floors of the 45 building, branch pipesf being connected thereto and running horizontally between the floors (Zand ceilings g thereof. Supplemental branch pipes h tap the pipes f andenter the rooms of the building at any desired point,

said pipes being provided with flaring mouthpieces 1 opening into therooms in different directions, and with ordinary dampers or valves 70,by means of which they may be readily closed. An opening m is formed inthe eduction-pipe o, and a curved plate 1.) is fitted to slide in ways gon said pipe and close said opening. A bag or receptacle D composed ofreticulated fabric, preferably wire, cloth, is suspended within the pipeo, opposite the opening m, by means "of a plate t, which rests uponstuds w in said pipe, said bag being filled with disinfecting orfumigating material.

In the use of my improvement fresh air is admitted into the blower Bthrough the pipe w, and is forced thereby into the pipe '0, whence itmay be readily admitted into the rooms by opening the valves in thebranch pipes h. Any suitable disinfectant may be employed in the holderD, and the air being 70 forced through the same by the blower becomesthoroughly impregnated therewith. Fumigating material may also beemployed and can be readily lighted in the holder through the openingat, the smoke from the burning material being rapidly carried into therooms by the current of air in the pipe 1* when the valves 70 areopened.

It will be understood that the holder D can be readily removed throughthe opening m to be refilled or replaced by another containing freshmaterial.

Havingthus explained my invention, what I claim is 1. In a ventilator,the combination of a rotary blower provided with an induction-pipe forsupplying fresh air thereto, an eductionpipe connecting said blower withdifferent stories of the building, said eduction-pipe being providedwith a side opening and with 0 a door for closing said opening, branchpipes leading from the eduction-pipe into the different rooms of thebuilding and provided with mouth-pieces having valves for closing: thesame, and a receptacle detaohably disposed in said eduction-pipeopposite said opening, and adapted to contain disinfecting material forimpregnating the air as it passes through said pipe, substantially asset for forcing air through said pipe,substant-ially forth. asdescribed.

2. The eduction-pipe v, provided with the T T opening m, door 13, andstuds 10, in eombina- W ILLIAM OLER' 5 tion with the reticulated holder1), adapted Vitnesses:

to contain disinfecting material and provided E. M. SPINNEY, with theplate t, and adjunetive mechanism 0. M. SHAW.
